To @ZZ who'm/ t may concern:

Be it known that l', JEROME B. Sncon, a l citizen of the United States, and a resident of y' Derby, in the county of New Haven and j Stato of Connecticut, have invented a new and useful Improvement in Type-Vllriter Oarriag'es,` of which the following is aspeciiication,

My invention relates to paper-guides for type-Writer carriages and means for retaining the paper'- in proper contact with the platen during the printing operation.`

The improvements consist particularl in means hereinafter described and claime for guiding the a er thereon and means for retracting saidpc ips when a new sheet is to be introduced.

In the accon'ipanying drawings, iiigure is av plan view of a type-writer-carriage illustrating my invention, showin, a paper-holding bail, hereinafter describer thrown back for the introduction of a fresh sheet. li'ig. 2 is a front view of the same, showing the paper-holding bail in operative position. iig. 3 is an end View of the carriage. Fig. 4T is an end view, partly in section, showing the paerholding bail thrown back as in Fig. l.

ig. 5is a detail end view of an elastic margin or column gage or indicator, showing 1n section the horizontal bar on which it is mounted and slides.

l represents the cylindrical platen, and 2 a ratchet gearWheel mounted on its end as a means for communicating step-b'y-step rotation to the platen for yline-spacing. The platenloperating mechanism being fully described in my application Serial N o. 223,578, of which the present is a division, need not be described in detail here.

i9 represents the paperfguide table, which is formed with a longitudinal recess `for a purpose hereinafter described.

21 represents rollers mounted on springs 22, pressine the pa er against the platen to 'effect the faced of t re' paper by rotation of are paper-guide clips 23.

'lne platen and guide-tal e are mounted in a vertically-movable frame to effect the shift of' the. platen, as customary with front-strike machines, so as to Iprint either one of two types carried by eac type-bar. In order to reduce the power required to thus raise the platen and.` its accessories, the weight of the vertically-shifting frame and parts carried thereby is partially counterbalancedA by springs 24. n

represents pressurerollers at front of the platen carried by hollow shaft 36, turning on an inner shaft 37, on the ends of which are keyed cams 38, bearing against antifrictionrollers 39, turning on fixed studs One of the cams 38 is provided with a projecting finger-piece 40, the de )ression of which turns the inner shaft 37 and its end cams 38 so as to retract the rollers 35 from the platen, against which the r are Vnormally held by springs il the shaft 36 sliding at its ends in a direction radial lto the platen in inclined slots 52 (shown in dotted lines, Fig. 3) in the end plates'of the platen-frame.

4S .represents elastic margin or columnor indicators composed of a slidarest and a guidedinger 48, of spring metal, mounted on the rest 48, bent downwardly and upwardly into U shape andcurved to avoid the platen. The slide-rest 48 is mount-' ed to slide longitudinally ofthe platen on theV horizontal scale-barv 49 and is held against accidental displacement on said scale-bar 49 by means of pressure of the finger 48'*v a lainst the under side of the scale-bar 49. 'ilo in sure proper degree of pressure or friction of linger 48a against bar 49, finger 48',L is formed with a nose or bar 49. A y

50 represents a supplemental clip compris ing a bail pivoted by the ends of its arms at 51 in the platen-frame and resting Within the recess 20 in the paper-feed table when turned back out of use, as shown in Fig. l and Fig. 3 and infull lines in Fig. 5. Its se is to hold very lug 48h, which engages the` still paper to the platen, for which purpose .it l

is turned forward over the paper to the position shown in Fig. 2 and in dotted linesin In ordinary cases and with common f Fie. 5. ilezible paper the paper-guides 23 alone snftice for this function.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. The combination of a rotatable platen,

f a paper-feed table 'having a longitudinal recess parallel with the rotatable platen, suit.

able clips by which the paper passing from said feed-table is guided and held in contact with the platen and a supplemental peper clip adapted Afor option al use or disuse during the printing operation and retractable when out of use into the recess in the feed-table, substantially as described.

2. In a type-writ'ng machine, the combination of a rotatable platen, e reeessed pa per-guide table provided with suitable guides to keep the paper in proper Contact With the platen, andv a supplemental paper-clip for emergency use adapted. to apply additional pressure to the paper and 'capable of being retraeted. within a recess in the paper-guide table when not in useI substantially as set forth.

3. ln a type-writing machine, the co1nbi nation with a platen and a platen-frame, of a trausverselydnovable shaft mounted in slots in said frame, pressure-rollers mounted on said shaft,y springs for holding said shaft to ward said, platen to maintain the rollers against the surface of the platen a liancboperated cani r-nounted on said. shaft and en- I geging the pletenreme to separate the rollsure-rollers mounted on said shaft and adapted to rest against the surface of the platen; a vcam on seid shaft adapted to engage the platen-frame, to separate the rollers from the surface of the platen and. spring means resistin the action of seid earn. i

5. n n type-Writing 'machin-e, the combination with a platen and a platen-frame, of a springcontrolled shaft, pressure-rollers mounted on said shaft und adapted to engege the surface of said plu-ten, a earn mounted on seid shaft and adapted to `torce the rollers from the surface of the platen and an antifriction-roller mounted on the frame in engagement with said cam.

6. ln e type-writing machine7 the combi nation with a platen and a platen-frame, e spring-controlled shaft Inovably mounted in said frame, a hollow shaft on seid spring-controlled-sha'ft, pressure-rollers carried by seid hollow shaft und adapted to bear against the surface of the platen and antifriction-cam means for forcing said shaft away from the laten in opposition to said spring-control ing means to carry the rollers away from the surface of the platen.
